The impact of curricular reform efforts that are incorporated into the Statewide Systemic Initiatives (SSIs) program were examined at the item level using data from the 1990, 1992, and 1996 NAEP state administrations. The item-level data from the State NAEP for grade 8 from 1990, 1992, and 1996 and for grade 4 from 1992, and 1996 were examined applying methodology developed for the study of dif...

H susceptibility is a measured by how easily a person can be hypnotized (2). There are several types of scales used; among all of them, the Harvard Group Scale of Hypnotic Susceptibility (HGSHS) (3,4,5) and the Stanford Hypnotic Susceptibility Scales (SHSS) (4,5) are the most common (6). Both of the Standard scales and Harvard scales are connected to the traditional perspective of hypnosis. The...

In this research, we use Item Response Theory based model for computing procedural knowledge of a sample of primary school children solving fraction addition exercises. For each exercise, the model needs to automatically construct a solution graph. We have explored different strategies for building such graphs and the effects they have on the quality of the model predictions. The results obtain...

This study investigates differences in the partial scoring performance of examinees in elimination testing and conventional dichotomous scoring of multiple-choice tests implemented on a computer-based system. Elimination testing that uses the same set of multiple-choice items rewards examinees with partial knowledge over those who are simply guessing. This study provides a computer-based test a...

SIETTE is an efficient web-based implementation of a Computer Adaptive Test. The inference machine used is based on Item Response Theory. New enhances in the evaluation mechanisms, question selection and finalization criteria have been introduced. New evaluation mechanism allows giving structured knowledge estimation about all topics evaluated in a test. Question selection criteria are able to ...

The purpose of this study is to investigate the effectiveness of response modes by item and feedback type in a webbased language learning program. The subjects of this study, 122 Korean tenth graders learning English as a foreign language, were placed into groups of four and were given a web-based language learning program consisting of two different varieties of item type (multiple choice and ...

The validation of models for skills assessment is often conducted by using simulated students because their skills mastery can be predefined. Student performance data is generated according to the predefined skills and models are trained over this data. The accuracy of model skill predictions can thereafter be verified by comparing the predefined skills with the predicted ones. We investigate t...

One of the most popular student modeling techniques currently available is Constraint Based Modeling (CBM), which is based on Ohlsson's theory of learning from performance errors. It focuses on the domain principles to correct faulty knowledge and assumes that a student will reach a correct solution without violating these fundamental domain concepts. However, even though this is a powerful and...

This study was an attemptto provide detailed information of the strengths and weaknesses of test takers‟ real ability through cognitive diagnostic assessment, and to detect differential item functioning in each test item. The rationale for using CDA was that it estimates an item‟s discrimination power, whereas clas- sical test theory or item response theory depicts between rather within item mu...
